During the run south from Fort William behind LNER K1 2-6-0 2005 on 14th November 1987, aside from the weather which for the time of year was superb, the highlight of the run for me was the climb from just beyond Arrochar & Tarbet to the summit after the Glen Douglas passing place.
The sun had set some time before but there was still light in the sky over the mountains to the west and as we climbed high above Loch Long it was one of those occasions when I wished I could have been in two places at once. Seen in the dusk from the road at the other side of the loch we must have made a superb sight with the smoke hanging in the still November air!
But then I would have missed this excellent recording, which begins as 2005, after slowing through the loop at Glen Douglas, completes the climb with the loco's exhaust echoing back from the trees on the final 1 in 56 gradient to the summit.
